4.0 DATA PRESENTATION, ANALYSIS OF THE RESULTS and discussion of the findings

4.1 Introduction

This chapter analyses the empirical data in an attempt to make analysis of occupational health and safety in building construction sites project in Dar es Salaam region, Kinondoni district. It covers the statutory requirements of health and safety in construction industry as propounded by different organizations which deal with projects of building constructions.

4.2 Profile of the Respondents

The survey was conducted with 120 people working in construction sites.80% were male and at least 58% have primary school education level. Majority of the respondents were, 82% and 60% were builders and work in residential building construction projects.

4.2.1 Health and Safety Mechanisms and Policies Guiding Construction Industry in Tanzania

Supervisors in responding the interview guide question all declare there is no clear policy governing health and safety in construction industry. So 100% of supervisors declare such a thing and even OSHA officers as well as CRB.

In this section respondents explained various health and safety mechanisms which they use in construction industry. Most of them based on the following things;

Site organization; Everything you need to know about organizing a safe and healthy construction site.

Slips, trips and falls; Assess, eliminate and control the risks of slips, trips and falls on construction sites.

Work at height; The hierarchy of controls for working at height, from working at ground level, using towers, scaffolds, platforms and ladders and, as a last resort, fall restraints and safety netting.

Structural stability; Assess the risks and prevent unintentional structural collapse during alterations, demolition and dismantling; and the measures you need to take to prevent accidents in excavations.

Cranes; All lifting operations involving lifting equipment must be properly planned by a competent person; appropriately supervised; and carried out in a safe manner.

Electricity; Work safely with power supplies and electrical equipment; map overhead power lines and underground cables to prevent accidental contact with machinery.

Fire; Identify the risks of fire; control combustible materials and ignition sources; and make it clear exactly what to do if fire does break out.

Mobile plant and vehicles; Assess the risks, establish competence to operate and control access to telehandlers, excavators, mobile work platforms, dumpers and road vehicles.

Demolition; All demolition, dismantling and structural alteration should be carefully planned and carried out by competent practitioners.
Since there no clear policy in the issue concerning health and safety Occupational Safety and Health Authority in Tanzania (OSHA) Act 2003, require the Employer to provide a health and safety session in any construction sites. In this study it is found that 102 people out of 120 which is equal to 85% has got a knowledge on first aid kit and they have it in their field area. Also 18 people out of 120 have not got knowledge about first aid kit and they even don't have it in field area.
